Fix PR2697 by rewriting the '(X / pos) op neg' logic. This also changes a couple other cases for clarity, but shouldn't affect correctness.

Allow scalarrepl to treat an all-zero GEP just as bitcast.2008-10-06T16:23:31ZMatthijs Kooijmanmatthijs@stdin.nl2008-10-06T16:23:31Zurn:sha1:5fac55fafb53fde5c548bcd08e07418e9d8e549f
This includes not marking a GEP involving a vector as unsafe, but only when it
has all zero indices. This allows scalarrepl to work in a few more cases.

shifting and masking inside a bswap expr. This allows it to handle
the cases from PR2842, which involve the intermediate 'or'
expressions being shifted, not just the input value.

Since the pass is currently run before SROA, this may be
quite helpful. Requested by Chris on IRC.
